Pest risk analysis of European grapevine moth Lobesia botrana in China

Aim] European grapevine moth, Lobesia botrana (Lepdoptera: Tortricidae), is listed as a quarantine pest in China. It can seriously hurt the grape and forestry industry if it were to invade China. The risk analysis of invasion in China can provide the basis for quarantine and early warning of the pest. Method] The morphological and biological characteristics of L. botrana were obtained based on the relevant literature. According to the general pest risk assessment method, qualitative and quantitative analyses of invasive risk were conducted based on the distribution of the pest, potential hazards, economic importance of its host, the possibility of spreading and the management difficulty. Result] L. botrana is a great potential threat to China with the risk value of 2.14, which indicate that it is highly dangerous pest. Conclusion] It is suggested that the quarantine departments should strengthen quarantine actions in the provinces and autonomous regions such as Xinjiang in order to prevent its introduction to China.
